Larry, R41 1214 indicates a 1961 Chrysler or Imperial 413 engine built on 12-14-60. Not sure about the diamond. Not a 300G engine unless it also was stamped HP.

It has had 7,000 US dollars invested in it. might put it in Barber's 300k. It is stamped R41 below that is 1214 and a diamond stamped. Possibly the diamond is oversized tappets. Any comments as to the year the R signifies? When I learn what was done for it will offer it up to the list first. jettlarry@xxxxxxx <mailto:jettlarry%40aol.com> Larry Jett 510-794 7911 Newark CA [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylangYahoo!
